William pursued a master’s degree at the Sao Paulo State University (UNESP/Rio Claro/Brazil -2012 - receiving the maximum possible grade: GPA 10.0/10.0 - with three peer-review articles published being one as the first author) studying hydrophobic Sonogels. From 2012 to 2016, William concluded his Ph.D. in Physics at Technological Institute of Aeronautics (ITA/ São José dos Campos/Brazil - GPA 9.13/10.0 - with four peer-review articles published being three as the first author), in the most prestigious military institution in Brazil with studies on atomic layer deposition (ALD) with titanium dioxide thin-films, being the first thesis in the ALD field in Latin America. Due to budget cuts by the Brazilian Government, he stopped his career between March of 2016 until March of 2017, a period of low scientific productivity. In 2017, William started with a lecturer position at Centro Universitário Adventista de São Paulo - Brazil, with responsibilities in several classes. Late in 2017, the researcher re-started his career at the University of São Paulo (USP) with a Postdoctoral Fellowship received an independent grant through competitive funding (success rate 5%) where William was the principal investigator (PI). Also, William participated as a jury in two juries of an academic degree of a master's degree and another of a doctoral degree at USP. As part of the project, he performed short research stay at the International Iberian Nanotechnology Laboratory (INL) at Nanofabrication for Optoelectronic Applications group, under the project “Passivation of Semiconductor interfaces for CIGS solar cells.” As dissemination, he participated in an interview on a TV show, namely, Educação at Novo tempo TV, talking about engineering and technology (2017). Also, he taught a course of dissemination of knowledge of Fabrication and Electrical Characterization of MOS Solar Cells at the University of São Paulo, for a general audience (2018). Projects: 1) he was the principal investigator (PI) of a Postdoctoral Fellowship at USP with the most prestigious Brazilian funding agency; namely, the Sao Paulo Research Foundation (FAPESP)- grant number 2016/17826-7 (budget 40k€) was about the fabrication of MOS solar cells based on silicon and dielectrics growth by ALD; and, 2) he is an associated researcher in the project: Synthesis and microbiological analysis of polymer substrates coated with TiO2 or Al2O3 ultra-thin films by atomic layer deposition technology - grant number 2018/01265-1 (budget 38k€) that was approved by FAPESP. (Technological Institute of Aeronautics (ITA)), two Brazilian universities (Universidade Brasil and the University of São Paulo). In June 2019, willing to increase his technological background, he decided to move to Europe. He started a second postdoctoral fellowship at the University of Aveiro - Portugal studying thin-films of kesterites (CZTS) or chalcopyrites (CIGS), using photoluminescence spectroscopy (PL), time-resolved photoluminescence, Raman spectroscopy, and measurements and analysis of conductivity results as a function of temperature. William track-record in proposal writing is outstanding as these shortlists of achievements demonstrate, considering the complex economic and social conditions that Brazil is currently facing. Furthermore, he has been collaborating with several international institutions and, he is active elaboration/management of individual projects, teaching, science dissemination through articles, books, open science, and seminars for all audiences.
